I will use the injection again. Was working very well. I am sure the 4th cylinder looks like that from busted intake guide oil seal.
The turbo is HTA green from evo X. I wanted twin scroll bad enough to retrofit the kit. Been on car for almost two years.
The iridium plugs are the best I have used. Far better than the copper.
